wat to explain.... thats the reason....
6@skygirl: yeah it has been experimentally found out yet abhirup has found the problem that i was facing! he actually wrote the step which is endothermic and hence he cleared my doubt without performing the experiment so the doubts can be cleared without performing the experiment!!!!!!!
cheers!!!!!!!!
